GTX 650 huge fps drops

DarkEye1337 · Feb 12, 2014

Hey,

First of all, I've been experiencing this problems for months now, the day I went from Radeon HD6570 to my current GTX 650. I forgot about this problem the whole time, since I stopped and now want to get back into gaming.

All my games (ALL OF THE 60) just have like huge fps drops out of nowhere.
I can't even run them on SUPER-LOW settings without still getting "awesome" drops.
So if anyone knows what's causing this, please let me know.

My specs:
CPU: AMD Phenom II X4 965 Black Edition 3.4Ghz
GPU: NVIDIA GeForce GTX 650 1GB
RAM: Corsair DDR3-1333 4GB.
MOTHERBOARD: MSI 760GM-P23(FX)
OS: Windows 7 Ultimate - x64 BIT
NVIDIA DRIVERS UPDATED TO LATEST VERSION!

I match recommended specs of all my games.
So I don't see what's the problem.

Thanks guyes.

Power supply?
Which 650 do you have?
Did you have better performance when the card was new?

It could be some app/software which drains power from both cpu and gpu or you have low power supply

I really have no idea man, it's quite old but it has nothing to do with it, I'm certain.
It doesn't have any label I can see, same from the inside.

Reason I'm sure is that I had 1 or 2 months back bought a new power supply, which was from msi and had like 750 watts, and that didn't fix my problem as well, so I got mad and broke the damn thing. Now I'm using my old one.

Any other ideas?

cst1992 :

It's just the GTX 650 1GB nor Ti nor Ti Boosted, and no, directly when I installed the new gpu, I reformated my pc.
And it had problems, everything all drivers are installed, everything.

Johncamary :

I don't have any of those.

What I do know guyes, is that when I play a game I can sense when the fps is about to drop, thanks to the GPU or CPU fan it goes like really fast, woooooooooooooooooooooooooooooooooooo then goes normal and then i play with normal fps for like another 4-5 min then again woooooooooooooooooooooooo again lags.

Try running some synthetic benchmarks, such as PerformanceTest.
Guys from all around the world will have uploaded similar benchmarks; you can compare your performance.
Have you been having high temperatures under load of your graphics card?

cst1992 :

I remember getting up to 50* degree celcius, I'll run the PerformanceTest now and get back to you.

What I mean is that, which 650?
Palit, EVGA, Gainward, ASUS, PNY, MSI, Galaxy?

If your fan spins fast, that means you have temperature problems, causing your card to throttle.
Did you overclock your card? Is it factory overclocked(Something like SuperClocked or OC or some Special Edition or something)? Is the rest of your room hot or cold?

This is it: http://www.msi.com/product/vga/N650-1GD5-OC.html#/?div=Specification

I think it's overclocked as it's name is: MSI GTX 650 OC, 1GB
OC = OverClocked if I'm not mistaken.

These are the results of PerformanceTest

I don't know if this is an issue, but most of the time I set my cpu fan to 50% because it makes too much noise to play a game, maybe this is one of the problem it get's hot and then lags?

cst1992 · Feb 12, 2014

Could be.
Your 3d benchmark score is same as a 550Ti -- that is normal, as it is around the same performance as a 550Ti. However, as it is overclocked, it should have slightly higher performance.
Try underclocking your 650 to 1058 MHz core, 1250 MHz(or 2500MHz whichever it shows) memory clock. Those are the stock clocks for the 650.
What happens when you set the fan to normal? The fan spinning too slow should cause the card to heat up.

UPDATE: Do you get something like 405 MHz core, 405 MHz memory clock(use GPU-Z to check)? Then set your fan curve to default.
That indicates your card getting too hot, and the NVIDIA drivers kicking in, causing it to get stuck at those lower clocks, reducing performance considerably. It also sometimes indicates an unstable overclock, but I'd say you didn't try that.

I can't control my GPU (card) fan speed, only CPU (processor) fan speed.

cst1992 · Feb 13, 2014

Huh? You yourself said you set it to 50% max.
BTW, I'm thinking the other possibility of the card downclocking itself to cool down must be the issue.
You can download MSI afterburner and downclock your card, probably your best option.

cst1992 :

I sed I can control my CPU ONLY. I CAN'T control my graphics card.

I'll try that.

DarkEye1337 · Feb 14, 2014

Ok, so after reformating my entire hdd, I installed Windows 8.
Now, I managed to track everything this is what happens.

My CPU (processor) starts going from 5 - 10% to 80 - 98% while playing games.
So I guess it's not my GPU after all...

Should I upgrade my CPU?

Thanks

You should.
